Prefilter and Post Filter Cartridges

You must replace the pref!lter cartridge often to pro- tect the RO membrane from being destroyed by chlorine,

and/or from plugging with sediments in your water

supply. If the water supply contains both chlorine

and sediments, replace the prefilter cartridge at least

every 6 months of product water use. Replace more

often than 6 months if it begins to plug with sedi- ments.

If the water has sediments only, with no chlorine, you may notice a slower making of product water as the

prefilter collects the sediments. When this occurs, re-

timer. (monitor models).

*Note: Use a lubricant approved for use on a potable water supply.
